The issue you describe looks like [1] which was fixed in Debian not too
long ago by upgrading to 1.7.2. I couldn't find the relevant upstream
bug mentioned in the changelog. If someone could point us to the
relevant bug/commit it would be appreciated :)

You may want to open a bug on Launchpad to have the fix backported to
Ubuntu.
